If it could save a person's life, would you find a way to make it faster? "If it could save a person's life, would you find a way to shave ten seconds off the boot time?" [Jobs] asked. Kenyon allowed that he probably could. Jobs went to a whiteboard and showed that if there were five million people using the Max, and it took ten seconds extra to turn it on every day, that added up to three hundred million or so hours per year that people would save, which was the equivalent of at least one hundred lifetimes saved per year. "Larry was suitably impressed, and a few weeks later he came back and it booted up twenty-eight seconds faster," Atkinson recalled. "Steve had a way of motivating by looking at the bigger picture."

Solution to evaluation and back again A second reason the systems engineer’s design is never completed is the solution offered to the original problem usually produces both deeper insight and dissatisfactions in the engineers themselves. Furthermore, while the design phase continually goes from proposed solution to evaluation and back again and again, there comes a time when this process of redefinement must stop and the real problem be coped with—thus giving what they realize is, in the long run, a suboptimal solution.
